Basically it just wraps together nix shell -c and nix-index. You stick a , in front of a command to run it from whatever location it happens to occupy in nixpkgs without really thinking about it.

Installation

either install it in your nix environment

nix-env -f '<nixpkgs>' -iA comma

or add this snippet to your NixOS configuration.

environment.systemPackages = with pkgs; [ comma ];
